WASTE CONTROL FOR FLUSH-TANKS.

Application filed April 8,

T 0 all whom it may concern:

Be it known that I, RAYMOND H. KEEVAN, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in WVaste Controls for Flush-Tanks; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

This invention relates to new and useful improvements in waste control for flush tanks.

The object of the invention is to provide a waste control of this character which will be noiseless in operation, which will be very durable and which can be readily installed in the tank.

My invention, therefore, consists in the features of construction and combination of parts hereinafter described in the specification, pointed out in the claims and illustrated in the accompanying drawing.

Referring to the accompanying drawing, 7 Figure 1 is a top plan of a Waste outlet embodying myidea.

Fig. 2 is a central vertical section through the same. 7

Again referring to the drawings, 3 represents the bottom portion of a flush tank for a closet, which is provided with the usual opening' f forthe waste. My device comprises a hollow base portion 6 which is provided with an outlet pipe section or connection 7 which is preferably formed integral with thebase'portion and is adapted to extend down through the opening 4 .in the bottom of the flush tank. The connection 7 is screw threaded so asto receive a clamping nut 8 and also the pipe section (not shown) which extends to the" closet bowl. In the top of the base member 6 is formed an outlet opening 10 having a valve seat 11. In the top of the base member 6 is also formed a screw threaded opening 13 adapted to receive the end of the overflow waste pipe 14. On the top portion of the base 6 is mounted a hollow casing 16 which fits down on the member 6 so as to inclose the valve seat 11. The casing 16 is provided with a dish-like extension 17 which communicates with the interior of said casing. At one side of the casing 16 is formed an opening 18. On top of the casing 16 is mounted a forked standard 20, and on this standard is pivoted a le- Specification of Letters Patent.

ver 21. The valve for closing the outlet is in the form of a flat disk comprising a metallic plate 23 on the bottom side of which is arranged a gasket 24 of rubber or other suitable material. Theplate 23 is provided with a centrally arranged stud 25 adapted to receive a clamping nut 26. From the bottom of the stud 25 a guide rod 27 extends downwardly and passes through an opening 28 in a bracket member 29 formed on the inside of the pipe section 27. ,The object of the guide rod is to centralize the valve 23 and insure its proper position on the valve seat 11. The valves are connected wit-h lever 21 by means of a link 30. From the outer end of lever 21 is hung a counterbalancing and retarding member which comprises a circular disk or plate 34 which is lighter than the valve and; is preferably provided with an annular flange 35. This plate or disk 34 is slightly smaller in diameter than the interior diameter of the dish-shaped extension 17 of the casing 16and is provided with a hollow stem 36. The stem is connected with the lever 21 by means of a link 37. A pin 39 is arranged vcentrally in the dishshaped portion 17 and extends up into the hollowstem 36 of the retarding member. A linkshown at 10 is connected to the valve carrying end of the lever 21, and a chain (not shown) is connected thereto and is car ried down over the edge of the flush tank. The chain is suitably supported so that a down pull on the said chain will elevate or raise the valve carrying end of the lever 21.

The operation of my device is as follows :When the tank is full and the flush outlet closed the members of the device will be in the position shown' in Fig. 2,that is, the valve will be on the valve seat 11 and the retarding device will be slightly above the dish-shaped portion 17. When it is desired to start the flush in operation the chain 40 is operated, which raises the valve carrying end of the lever 21 lifting the valve from the valve seat 11 and at the same time the opposite end of the lever 21 will be swung down, which in turn will shove down the retarding member into the dish-shaped portion 17. The water in the tank will then enter the casing 16 through the opening 18 and also through the top of the dish-portion 17 above the retarding member and will then flow down through the waste pipe. Now, although the retarding member is considerably lighter than the valve, the weight of the water above the retarding member and the suction produced by the water fiowing through the dish-shaped portion above the retarding member will hold the retard, ing member against the bottom of the dish; shaped portion-until practically all of the.

Water has been drained from the tank." As soon as the tank'is emptied of-thewater the valve Will move down on its seat by its own Weight, operating the lever 21 which inturn raises the retarding member 34 to its normal position. e

It has been found out that when using my valve the tank can be more completely drained than when using the old type of rubber ball valve. This of course furnishes more water .for the flush, making the flush more efficient.- Also,'as practically all the Water in the tank is utilized, it is possible to use a smaller tank Whenmy valve is employed.

Another important advantage secured by the use of my valve is the rendering of the flush practically noiseless. This noiseless action is due tothe; fact that, as the valve movesdown to its seat, tho retarding mem her is pulled up through the water still in the tank, and the resistance thus offered'prevents the valve from dropping suddenly on its seat. The relatively slow closing of the valve therefore eliminates all noise;

What I claim is 7 1. In a wastecontrol for a flush combination with a flush :tank having a Waste outlet of a hollow valve casing pro- Vvided withanopening in the side thereof and an outlet opening corresponding tothe outlet opening in the tank, a disk valve arranged to rest on and close said outletvopening in said casing, a lever pivotally. supported'adjacent to said casing, a link con-- necting one end of said. lever to said valve, a retarding device hung fromthe opposite end vof said lever adjacent to the opening in the side ofsaid casing and, means for operat-v ing said 1ever, the arrangement beingsuch that the waterwbefore'passing'through the opening in said valve casing i during the tank, the

flushing peration will pass over said retarding device;

2. The combination with a flush tank having an outlet in "the bottom thereof of a Waste control; comprising a hollow base .member having an outlet pipe extending down through the outlet opening in the-tank "and provided with an outlet openingin'the top in line with-said pipe outlet, a disk valve arranged to rest on said outlet opening, a hollow casing arranged over said outlet, said casing having a dish-shaped extension, a retarding device consisting of a dish-shaped member arranged to move up and down within the dish-shaped portionfa lever pivotally supported near said casing, means connecting one end of said lever with the re tarding device and the other'endof said and means for operatlever with said valve i-ng said valve. V I v 3. The combination with a flush tank havprising a hollow base member having I an outlet pipe extending through the outlet opening in the tank, said base member also 'and' downwithin the dish shaped portion of the hollow casing, a lever pivotally sup} ported near said casing, means connecting V one end of said lever with the're tardi ng device and the other end of said lever with said valve, the arrangement being such that said valve willoverbalanc'e said retarding device when r theflush tank is empty and means for operating said lever. 7 In testimony whereofl sign the foregoing specification in the'presenceof two witnesses.
